You might want to contact Big Winds or The Gorge Shop in Hood River, Oregon. I should also point out that Big Winds is a Starboard dealer. While visiting the Gorge, I was able to pick up a variety of longer M6 screws at these shops with a Phillips head configuration.

Earlier, in my local area at a speciality hardware company, I was able to get some longer M6 screws, but they had Allen head configurations, which meant that I always had to keep track of little Allen tools. Kind of a pain, and they&#39;re also subject to corrosion.
